dscp
Syntax dscp dscp-name fc fc-name profile {in | out}
no dscp
Context config>qos>network>ingress
Description This command creates a mapping between the DSCP of the network ingress traffic and the
forwarding class for GRE or IP packets.
Ingress traffic that matches the specified DSCP is assigned to the corresponding forwarding
class. Multiple commands can be entered to define the association of some or all 64 DSCP
values with the forwarding class. For undefined code points, packets are assigned to the
forwarding class specified under the default-action command.
The no form of this command removes the DSCP-to-FC association. The default-action then
applies to that code point value.
Default n/a
Parameters dscp-name — specifies the DSCP to be associated with the forwarding class. The DSCP
value is derived from the most significant six bits in the IP header ToS byte field
(DSCP bits). The six DSCP bits define 64 DSCP values used to map packets to
per-hop QoS behavior.
A maximum of 64 DSCP rules are allowed on a single policy. The specified name
must exist as a dscp-name. Table 31 lists all the valid DSCP names.
fc-name — specifies the forwarding class name with which the DSCP will be associated
Values be, l2, af, l1, h2, ef, h1, nc
Default be
profile {in | out} — all packets that are assigned to this forwarding class will be
considered in or out of profile based on this command. In case of congestion, the
in-profile packets are preferentially queued over the out-of-profile packets.
Values in, out
Default out
